* The factory setting for I2C slave address is 0x28, 0x36 or
|

|
* 0x46 depending on the interface type selected from the ordering information.
|

|
|
* The address is always followed by a write bit (0) or read bit (1).

* The default hexadecimal I2C header for read access to the sensor is therefore 0x51,
